Bachelor in Electrical & Electronics Engineering, major in Automation & Control

Ho Chi Minh city University of Technology - HCMUT

Year of graduation: 2016

GPA: 7.77/10

Graduate thesis: 3D printing with robot arm

Scorbot ER 5 plus manipulator

SCORBOT ER 5 plus

Filament extruder

3Doodler 2.0

3Doodler 2.0

Hacking the 3D pen

3Doodler 2.0 control port

Control port has 3 pins: VCC, GND and digital input

Slicing 3D object into meshes and control print paths

Algorithm taken from SuperSkein:

MaskedRetriever/SuperSkein

Print paths are represented in G-code, then translated to ACL commands and sent to Scorbot's driver via RS232.

2 separate mini CLI programs: slicer and intepreter. Both written using C#.

After graduation

Programming

Decide to work in IT field to gain industry experience and fortify programming skills

2016-2017: Hitachi Vantara Vietnam

~~NewTech department~~

Hitachi Vantara Vietnam

Research potential technologies to help company kickstart new business as solution provider beside outsourcing business.

Constraint programming

A sub-field of Artificial Intelligence

Gecode

Gecode

Google's OR-tools

Google's OR-tools

To put it simply:

  • Problems are defined as finite search space and constraints.

  • Search strategies varies: breadth-first, depth-first, score-based, etc..

  • Constraints are rules to eliminate unpromising search branches. In other word, constraints help shrinking the search space so the acceptable result is reached faster.

Others

  1. Support IoT team on hardware and embedded software development.

  2. Demo VR application to visualize network package path using Unreal Engine.

  3. Demo iOS app to track vehicles and traffic.

  4. REST API to tune hyper parameters of Deep Learning model.

2017-2018: Indie developer, freelancer

Indie developer

  • Made android app using Kotlin when Kotlin support is still beta.

  • Part-time web content evaluator. Experience how large-scale data labeling process really like.

2018-2020: DEK Technologies

System developer

Work as system developer. Has some minor contributions in Middleware development for Ericsson.

Acquired knowledge about:

  • Redundancy model for nodes in clusters.

  • Service life-cycle, logging and errors elevation in a system.

  • Traffic-generator for testing various functionalities of the system.

2020-now: Uniduc Robotic

Research collaborator

Robotic research collaborator

Projects involved:

  • Control BLDC motor for custom built robot joint. The work is based on ODrive project.

  • Design architecture and implement core parts of management hub for Uniduc's ecosystem. Also work as coordinator between different teams (vision, embedded, mobile app).

Details on management hub

  1. Daemon service on robot, connect to server using SocketIO.

  2. Flask server for management and provide API for clients.

  3. UI/UX design using Figma.

  4. Planning on integrating AWS's DynamoDB into the ecosystem for better scaling, backup and throughput.

Side projects

Mostly on Github: InNoobWeTrust

  • Made a clone of a popular puzzle game in Vietnam, using Unity3D. (EndlessPikachu)

  • Manga reader (Android): serious project as an indie developer. Failed to gain money for a living but learned a lot. (KINTAMAnga)

  • Learn Rust by making game: only use low-level display/sound library, no game engine, only pure Rust. (meme-connect)

Life-long learning

  • Learn things from courses on Coursera, Edx, Udemy, MOOCs on Youtube, etc..

  • Learn new languages as there is a chance. Good to boost the brain and allow seeing things in different perspectives.

Hobbies

  • Technologies, especially those around robots and artificial intelligence.

  • Learn new things, experience new ways of doing things. Gaining knowledge about everything.

  • Reading books.

  • Occasionally: art, music, psychology, cooking. Love to have a balance between both brain's hemispheres.
